What a Joke: April Fools 2010

Not only was there signage (a cornerstone of any good prank), some locations had employees wearing In-N-Out garb armed with promotional fliers. Photos began circulation on the web (here, here, here, here and here). New Yorkers began to salivate.

"You may be aware of a rumor or April Fool's Day hoax about In-N-Out Burger coming to New York City the Summer of 2010. This is not true. We are very sorry for any confusion this may have caused and have no idea how it got started. We want to make sure everyone knows that it is false..."

And who would do such a cruel thing to the burger-loving citizens of New York?

The gang at College Humor, obviously.

"We pulled a prank on New York City today where we tried to convince everybody In-N-Out Burger (our favorite West Coast burger chain) was opening up here. We made signs, hired actors to dress as employees, made flyers, etc. Lots of people bought it. Tons of people, actually. Then In-N-Out commented and the jig was up," according to a post on collegehumor.com.
